Description

本発明は、インナーロータ型のモールドモータに関するものである。   The present invention relates to an inner rotor type molded motor.

従来のブラシレスＤＣモータにおいては、駆動回路としてインバータ回路を用いたＰＷＭ制御を行っている（例えば、特許文献１参照）。   In a conventional brushless DC motor, PWM control using an inverter circuit as a drive circuit is performed (for example, see Patent Document 1).

上記のようなＰＷＭ制御を行うブラシレスＤＣモータにおいて、電食が発生する可能性がある。電食の原因としては、ブラケットの電位がフレームを構成しているモールド樹脂に対し電位が浮いた形になるため、安定しないということに起因している。即ち、ＰＷＭ制御のように高周波で制御する場合には、出力側のボールベアリングの外輪と同電位の出力側のブラケット及び反出力側のボールベアリングの外輪と同電位の反出力側のブラケットの電位が変わると、ボールベアリングの内輪と外輪を介した循環電流が流れ、この循環電流によって電食が発生する。
特開２００４−４８８２９公報 In a brushless DC motor that performs PWM control as described above, electric corrosion may occur. The cause of electrolytic corrosion is that the potential of the bracket is not stable because the potential is floating with respect to the mold resin constituting the frame. That is, when controlling at a high frequency as in PWM control, the potential of the output side bracket having the same potential as the outer ring of the output side ball bearing and the potential of the opposite output side bracket having the same potential as the outer ring of the counter output side ball bearing. When is changed, a circulating current flows through the inner and outer rings of the ball bearing, and electrolytic corrosion is generated by the circulating current.
JP 2004-48829 A

そこで、本発明は、インナーロータ型のモールドモータをインバータ回路でＰＷＭ制御を行っても、電食が発生しないモールドモータを提供する。   Therefore, the present invention provides a molded motor that does not generate electrolytic corrosion even when PWM control is performed on the inner rotor type molded motor by an inverter circuit.

請求項１に係る発明は、固定子がモールド樹脂によりモールド成形されてモータフレームが形成され、前記固定子の内周側に回転子が回転自在に配されたインナーロータ型のモールドモータにおいて、前記モータの出力側と反出力側の両方に円環状の金属製のブラケットがそれぞれ設けられ、そのうち一方のブラケットは外面の少なくとも一部が外部に露出するように前記モータフレームに埋設され、前記出力側のブラケットと前記反出力側のブラケットには、前記回転子の回転軸を回転自在に支持するベアリングがそれぞれ保持され、前記出力側のブラケットと前記反出力側のブラケットとが、前記各ブラケットの外部に露出する外面と前記モータフレームの外面に沿って貼り付けられた導電性テープによって短絡される電食対策とし、前記一方あるいは両方のブラケットに、前記導電性テープを覆うようにゴムが取り付けられたことを特徴とするモールドモータである。 The invention according to claim 1 is an inner rotor type molded motor in which a stator is molded with a mold resin to form a motor frame, and a rotor is rotatably disposed on an inner peripheral side of the stator. An annular metal bracket is provided on both the output side and the non-output side of the motor, and one of the brackets is embedded in the motor frame so that at least a part of the outer surface is exposed to the outside, and the output side The bracket and the non-output side bracket respectively hold bearings that rotatably support the rotating shaft of the rotor, and the output side bracket and the non-output side bracket are external to the brackets. and is the electrolytic corrosion measures short-circuited by the exposed outer surface and said motor frame pasted conductive tape along the outer surface, prior to On one or both of the brackets, a molded motor, characterized in that the rubber so as to cover the conductive tape is attached.

本発明のモールドモータであると、出力側のブラケットと反出力側のブラケットとが、導電部材によって接続されているため短絡され同電位となるため、循環電流が発生せず電食が発生することがない。   In the molded motor according to the present invention, the output side bracket and the non-output side bracket are connected by the conductive member and are short-circuited to have the same potential, so that no circulating current is generated and electrolytic corrosion occurs. There is no.

以下、本発明の一実施形態のモールドモータ１０について、図１及び図２に基づいて説明する。このモールドモータ１０は、ブラシレスＤＣモータである。   Hereinafter, a molded motor 10 according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. The mold motor 10 is a brushless DC motor.

図１は、モールドモータの縦断面図である。   FIG. 1 is a longitudinal sectional view of a molded motor.

鋼板を積層した固定子鉄心１２にプレモールドを施すことにより絶縁層１４を形成し、この絶縁層１４にコイル１６が巻回されている。これによってリング状の固定子１８が形成される。   An insulating layer 14 is formed by pre-molding the stator core 12 laminated with steel plates, and a coil 16 is wound around the insulating layer 14. As a result, a ring-shaped stator 18 is formed.

固定子１８の出力側の面には、ドーナツ状の配線基板２０が設けられている。この配線基板２０は、絶縁層１４によって構成された支持壁に支持されている。配線基板２０には、モールドモータ１０を駆動する電子部品が取り付けられている。このモールドモータ１０は、ブラシレスＤＣモータであるため、インバータ回路、論理回路等の電子部品が取り付けられている。   A donut-shaped wiring board 20 is provided on the output side surface of the stator 18. The wiring board 20 is supported on a support wall formed by the insulating layer 14. Electronic components that drive the mold motor 10 are attached to the wiring board 20. Since the mold motor 10 is a brushless DC motor, electronic parts such as an inverter circuit and a logic circuit are attached.

上記のように配線基板２０と固定子１８をモールド樹脂によって一体成形され、モータフレーム２２が形成されている。このモータフレーム２２は、円筒状であり、また、出力側の面には、金属製のブラケット２４が一体に埋設されている。この出力側のブラケット２４の内周側は、モータフレーム２２から露出した状態となっている。   As described above, the wiring board 20 and the stator 18 are integrally formed of the mold resin, and the motor frame 22 is formed. The motor frame 22 has a cylindrical shape, and a metal bracket 24 is integrally embedded on the output side surface. The inner peripheral side of the output side bracket 24 is exposed from the motor frame 22.

上記のようにして形成したモータフレーム２２の内周側に回転子２６が収納される。この回転子２６には、金属性の回転軸２８が貫通している。回転軸２８の出力側は、ベアリング３０を介してブラケット２４に回転自在に固定されている。   The rotor 26 is housed on the inner peripheral side of the motor frame 22 formed as described above. A metallic rotating shaft 28 passes through the rotor 26. The output side of the rotary shaft 28 is rotatably fixed to the bracket 24 via a bearing 30.

回転子２６の反出力側の回転軸２８は、ベアリング３２を介して反出力側の金属製のブラケット３４に取り付けられている。このブラケット３４はモータフレーム２２の反出力側の面に嵌合している。   The rotating shaft 28 on the counter-output side of the rotor 26 is attached to a metal bracket 34 on the counter-output side via a bearing 32. The bracket 34 is fitted to the surface on the non-output side of the motor frame 22.

出力側のブラケット２４と反出力側のブラケット３４の間には、導電性部材である導電性テープ３６が取り付けられている。具体的には、モータフレーム２２の外部に軸方向に沿って図２に示すような導電性テープ３６が貼り付けられ、一端部が出力側のブラケット２４に貼り付けられ、他端部が反出力側のブラケット３４に貼り付けられている。これによって、両ブラケット２４，３４が短絡されている。この導電性テープ３６としては、例えばアルミニウム製のテープ等がある。   A conductive tape 36 that is a conductive member is attached between the output side bracket 24 and the non-output side bracket 34. Specifically, a conductive tape 36 as shown in FIG. 2 is attached to the outside of the motor frame 22 along the axial direction, one end is attached to the output side bracket 24, and the other end is counter-output. Attached to the side bracket 34. Thereby, both brackets 24 and 34 are short-circuited. An example of the conductive tape 36 is an aluminum tape.

上記のように導電性テープ３６を取り付けたモータフレーム２２の出力側と反出力側に振動防止用のゴム３８，４０を取り付ける。   As described above, vibration preventing rubbers 38 and 40 are attached to the output side and the non-output side of the motor frame 22 to which the conductive tape 36 is attached.

上記構成のモールドモータ１０であると、導電性テープ３６によって出力側のブラケット２４と反出力側のブラケット３４とが短絡されているため、両ブラケット２４，３４の電位が同じとなり、循環電流が発生することがない。そのため、ベアリング３０，３２において電食が発生することがない。   In the case of the molded motor 10 having the above configuration, since the output side bracket 24 and the non-output side bracket 34 are short-circuited by the conductive tape 36, the potentials of both the brackets 24 and 34 become the same, and a circulating current is generated. There is nothing to do. Therefore, electrolytic corrosion does not occur in the bearings 30 and 32.

また、モータフレーム２２の外部にこの導電性テープ３６を貼り付けるだけであるため、他の部材に邪魔にならず、その貼り付けも容易である。   Further, since only the conductive tape 36 is attached to the outside of the motor frame 22, it does not get in the way of other members and can be attached easily.

（変更例）
上記実施形態では、両ブラケット２４，３４を短絡する導電部材として導電性テープ３６を用いたが、これに代えて導電性の線材（例えば、リード線等）や金属板から形成された部材を用いてもよい。 (Example of change)
In the above embodiment, the conductive tape 36 is used as a conductive member that short-circuits both the brackets 24 and 34. Instead, a conductive wire (for example, a lead wire) or a member formed of a metal plate is used. May be.
